(...)Elements of Deflation (2):

Is the Money Supply Growing or Not?

Today we tackle an economic concept called the velocity of money, and how it affects the growth of the economy. Let's start with a few charts showing the recent high growth in the money supply that many are alarmed about. The money supply is growing very slowly, alarmingly fast, or just about right, depending upon which monetary measure you use.

First, let's look at the adjusted monetary base, or plain old cash plus bank reserves (remember that fact) held at the Federal Reserve. That is the only part of the money supply the Fed has any real direct control of. Until very recently, there was very little year-over-year growth. The monetary base grew along a rather predictable long-term trend line, with some variance from time to time, but always coming back to the mean.

But in the last few months the monetary base has grown by a staggering amount. And when you see the "J-curve" in the monetary base (which is likely to rise even more!) it does demand an explanation. There are those who suggest this is an indication of a Federal Reserve gone wild and that 2,000-dollar gold and a plummeting dollar are just around the corner. They are looking at that graph and leaping to conclusions. But it is what you don't see that is important.

Now, let's introduce the concept of the velocity of money. Basically, this is the average frequency with which a unit of money is spent. Let's assume a very small economy of just you and me, which has a money supply of $100. I have the $100 and spend it to buy $100 worth of flowers from you. You in turn spend the $100 to buy books from me. We have created $200 of our "gross domestic product" from a money supply of just $100. If we do that transaction every month, in a year we would have $2400 of "GDP" from our $100 monetary base.

So, what that means is that gross domestic product is a function not just of the money supply but how fast the money supply moves through the economy. Stated as an equation, it is Y=MV, where Y is the nominal gross domestic product (not inflation-adjusted here), M is the money supply, and V is the velocity of money. You can solve for V by dividing Y by M.

Now let's dig a little deeper. Y, or nominal GDP, can actually written as Y=PQ, that is, GDP is the Price paid times the total Quantity of goods sold. Therefore, since Y=MV, the equation can be written as MV=PQ. But the point is that Price (P) is tied to the velocity (V) of money. You can increase the supply of money, and if velocity drops you can still see a drop in the "P," or inflation.

Now, let's complicate our illustration just a bit, but not too much at first. This is very basic, and for those of you who will complain that I am being too simple, wait a few paragraphs, please. Let's assume an island economy with 10 businesses and a money supply of $1,000,000. If each business does approximately $100,000 of business a quarter, then the gross domestic product for the island would be $4,000,000 (4 times the $1,000,000 quarterly production). The velocity of money in that economy is 4.

But what if our businesses got more productive? We introduce all sorts of interesting financial instruments, banking, new production capacity, computers, etc.; and now everyone is doing $100,000 per month. Now our GDP is $12,000,000 and the velocity of money is 12. But we have not increased the money supply. Again, we assume that all businesses are static. They buy and sell the same amount every month. There are no winners and losers as of yet.

Now let's complicate matters. Two of the kids of the owners of the businesses decide to go into business for themselves. Having learned from their parents, they immediately become successful and start doing $100,000 a month themselves. GDP potentially goes to $14,000,000. But, in order for everyone to stay at the same level of gross income, the velocity of money must increase to 14.

Now, this is important. If the velocity of money does NOT increase, that means (in our simple island world) that on average each business is now going to buy and sell less each month. Remember, nominal GDP is money supply times velocity. If velocity does not increase and money supply stays the same, GDP must stay the same, and the average business (there are now 12) goes from doing $1,200,000 a year down to $1,000,000.

Each business now is doing around $80,000 per month. Overall production on our island is the same, but is divided up among more businesses. For each of the businesses, it feels like a recession. They have fewer dollars, so they buy less and prices fall. They fall into actual deflation (very simplistically speaking). So, in that world, the local central bank recognizes that the money supply needs to grow at some rate in order to make the demand for money "neutral."

It is basic supply and demand. If the demand for corn increases, the price will go up. If Congress decides to remove the ethanol subsidy, the demand for corn will go down, as will the price.

If the central bank increased the money supply too much, you would have too much money chasing too few goods, and inflation would rear its ugly head. (Remember, this is a very simplistic example. We assume static production from each business, running at full capacity.)

Let's say the central bank doubles the money supply to $2,000,000. If the velocity of money is still 12, then the GDP would grow to $24,000,000. That would be a good thing, wouldn't it?

No, because only 20% more goods is produced from the two new businesses. There is a relationship between production and price. Each business would now sell $200,000 per month or double their previous sales, which they would spend on goods and services, which only grew by 20%. They would start to bid up the price of the goods they want, and inflation would set in. Think of the 1970s.

So, our mythical bank decides to boost the money supply by only 20%, which allows the economy to grow and prices to stay the same. Smart. And if only it were that simple.

Let's assume 10 million businesses, from the size of Exxon down to the local dry cleaners, and a population which grows by 1% a year. Hundreds of thousands of new businesses are being started every month, and another hundred thousand fail. Productivity over time increases, so that we are producing more "stuff" with fewer costly resources.

Now, there is no exact way to determine the right size of the money supply. It definitely needs to grow each year by at least the growth in the size of the economy, plus some more for new population, and you have to factor in productivity. If you don't then deflation will appear. But if the money supply grows too much, then you've got inflation.

And what about the velocity of money? Friedman assumed the velocity of money was constant. And it was from about 1950 until 1978 when he was doing his seminal work. But then things changed. Let's look at two charts, the first from Stifel Nicolaus Capital Markets.

Here we see the velocity of money for the last 109 years. The left side of the chart shows the velocity of money using both M2 and M3 (measures of the money supply.)

Notice that the velocity of money fell during the Great Depression. And from 1953 to 1980 the velocity of money was almost exactly the average for the last 100 years. Lacy Hunt, in a conversation that helped me immensely in writing this letter, explained that the velocity of money is mean reverting over long periods of time. That means one would expect the velocity of money to fall over time back to the mean or average. Some would make the argument that we should use the mean from more modern times since World War II, but even then mean reversion would mean a slowing of the velocity of money (V), and mean reversion implies that V would go below (overcorrect) the mean. However you look at it, the clear implication is that V is going to drop. In a few paragraphs, we will see why that is the case from a practical standpoint. But let's look at the first chart.

Y=MV

And then let's go back to our equation, Y=MV. If velocity slows by 30% (which it well has in terms of M3 – and it is down more than 15% in terms of M2) then money supply (M) would have to rise by that percentage just to maintain a static economy. But that assumes you do not have 1% population growth, 2% (or thereabouts) productivity growth, and a target inflation of 2%, which mean M (money supply) would need to grow about 5% a year, even if V were constant. And that is not particularly stimulative, given that we are in recession. And notice in the chart below that M2 has not been growing that much lately, after shooting up in late 2008 as the Fed flooded the market with liquidity.

Bottom line? Expect money-supply growth well north of what the economy could normally tolerate for the next few years. Is that enough? Too much? About right? We won't know for a long time. This will allow armchair economists (and that is most of us) to sit back and Monday morning quarterback for many years.

But this is important. The Fed is going to continue to print money as long as they are not confident deflation is no longer a problem. They can't tell us what that number is because they don't know. My guess is if they did tell us the markets would simply throw up, especially the bond market, which would of course make the situation from a deflation-fighting point of view even worse.

Sir, I Have Not Yet Begun to Print

Remember the story of John Paul Jones? An American naval officer during the American Revolution (the French gave him a medal, although the British referred to him as a pirate), he engaged a larger British ship off the coast Yorkshire. He literally tied his boat to the larger ship and they shot cannons and guns at point blank range. Legend has it that he was asked to surrender, as his ship was sinking. He is supposed to have replied, "Sir, I have not yet begun to fight!"

When faced with the possibility of deflation, I can almost hear Bernanke saying, "Sir, I have not yet begun to print!"

When will they know when enough is enough? When the velocity of money stops falling. When we see two quarters in a row where the velocity of money is rising, then it is time to start investing in inflation hedges.

Now, why is the velocity of money slowing down? Notice the significant real rise in velocity from 1990 through about 1997. Growth in M2 was falling during most of that period, yet the economy was growing. That means that velocity had to have been rising faster than normal. Why? It is financial innovation that spurs above-trend growth in velocity. Primarily because of the financial innovations introduced in the early '90s, like securitizations, CDOs, etc., we saw a significant rise in velocity.

And now we are watching the Great Unwind of financial innovations, as they went to excess and caused a credit crisis. In principle, a CDO or subprime asset-backed security should be a good thing. And in the beginning they were. But then standards got loose, greed kicked in, and Wall Street began to game the system. End of game.

What drove velocity to new highs is no longer part of the equation. The absence of new innovation and the removal of old innovations (even if they were bad innovations, they did help speed things up) are slowing things down. If the money supply had not risen significantly to offset that slowdown in velocity, the economy would already be in a much deeper recession.

The Fed has more room to print money than most of us realize. How much more? My bet is that we'll find out. Will they print too much at some point? Probably.
